The large purchase of K+H monitors initially came in anticipation of the Winter Games in Vancouver, as CTV, together with Rogers Media, outfitted the international broadcast center. "We had a huge number of television production control rooms to fill," explained Paul Sellers, manager of audio operations and technologies for CTV Television Inc. "And while the speakers were used initially in Vancouver, we intend to use them for the 2012 Summer Games in London and other major events throughout Canada."

Another 150 Klein + Hummel monitors had joined CTV in 2006 when the broadcaster purchased CHUM, a network that had already switched over to those monitors.

CTV operated seven production control rooms in Vancouver that used stereo pairs of either Klein + Hummel O 300s or O 110 monitors. Both units feature active design, the O 300 with three transducers and the O 110 with two. Audio production control rooms used a 5.1 array, with three O 110s in front, an O 810 subwoofer, and either two O 110s or two single-driver M 52s in the rear.

Avid editing suites used for the Winter Games duplicated the 5.1 setup. "For those editors who were new to mixing in surround, the M 52s made it easy," said Robert Miles, audio and communications engineering manager, CTV/Rogers Consortium for the 2010 Vancouver event. "They provided great rear field coverage without intimidation."

In addition, CTV had several dozen additional M 52s and M 52Ds (which feature a digital input) for miscellaneous use throughout the production environment.

These monitors have what I would describe as a 'simple' sound," noted Miles. "I don't really hear the speaker, just the program material."
